I like my Blue Ox Sway Pro WDH. It works great and I have never had any sway in over 6,000 miles with it in all kinds of conditions pulling a 3124KS. That includes a blowout at 70+ MPH fully loaded....never a hint of sway and was rock solid tracking straight as an arrow! But I hope you have the best of luck with this new device. Keep us posted. I would like to know how it works and where and how you did the install.
